PCD Polycrystalline diamond wire drawing dies
1. Polycrystalline diamon(PCD) has high hardness, good wear resisitance.
2. Compared with tungsten carbide, PCD wire drawing die has better wear resistance, supre abrasion of inner hole, strong shock reisitance, high drawing efficiency.
3. Price is much cheaper than nature diamond die, can draw larger size wires.
4. It is widely used in wire drawing industry, and will replace tungsten carbide drawing dies gradually.
